Discussion | Castilleja lineariloba is endemic to the western slope of the Sierra Nevada. Its chromosome number is 2n = 20, an apparent aneuploid reduction and documented by numerous counts. This diploid number is shared only with two very distantly related annual species endemic to central Mexico, C. gracilis Bentham and C. tenuifolia M. Martens & Galeotti.

Castilleja martini is sometimes treated as a subspecies of C. applegatei, but there are relatively consistent morphological discontinuities between these two variable complexes. See notes under 4. C. applegatei. Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
